Microsoft architect of identity Kim Cameron is quoted by Cade Metz in The Register as insisting that ‘ the “non-personal information” collected by Apple can be used to personally identify you.’ This follows up on Cameron’s earlier blog on Apple’s recent changes to its privacy policy. Well, maybe you’d expect some negativity whenever Microsoft and Apple comment on each other, but Cameron seems to be making a good argument that “if Apple releases your location and a GUID to a third party on multiple occasions, one location will soon stand out as being your residence… Then presto, if the third pary looks up the address in a “Reverse Address” search engine, the “random” GUID identifies you personally forever more.”
